Dynaquad, or DY, was a matrix decoder 4-channel quadraphonic sound system developed by Dynaco in 1969.[1][2][3]
The system originally had four speakers that were arranged in a diamond shape (centre-front, centre-left, centre-rear, centre-right).[4][5] Initially (first available in 1969 with th Dynaco SCA-80Q amplifier [6]), it was introduced as a derived (2:2:4) four channel "decoding" system based on the Hafler circuit, where the back channels played ambient sounds recovered from standard stereo sounds.[7] As such it wasn't used initially used as an encoding method (a similar approach was used on the Electrovoice Stereo-4 system).[8]
